Installation Tips
Wall Installation
The thermostat should be installed approximately 4 to 5 feet above the floor. Select an area with average temperature and good air circulation. Pick an installation location that is easy for the user to access. The temperature of the location should be representative of the building.
Do not install thermostat in locations:
- Close to hot or cold air ducts
- That are in direct sunlight
- With an outside wall behind the thermostat
- In areas that do not require conditioning
- Where there are dead spots or drafts (in corners or behind doors)
- Where there might be concealed chimneys or pipes
Removing The Private Label Badge
Gently slide a screwdriver into the bottom edge of the badge. Gently turn the
screwdriver counter clockwise. The badge is held on by a magnet in the well of
the battery door. The badge should pry off easily. DO NOT USE FORCE.
All of our thermostats use the same universal magnetic badge. Visit the
company website to learn more about our free private label program.

- Mount subbase on a flat wall.
- Use provided screws.
- Ensure drywall anchors are flush with wall.
- Push wires into wall.
Electrical Hazard
Failure to disconnect the power before beginning to install this product
can cause electrical shock or equipment damage.
Mercury Notice
All of our products are mercury free. However, if the product you are
replacing contains mercury, dispose of it properly. Your local waste
management authority can give you instructions on recycling and proper
disposal.
Mount Thermostat
Align the 4 tabs on the subbase with corresponding slots on the back of the thermostat, then push gently until the thermostat snaps in place.
Wiring
- Power Supply
- Factory-installed jumper, remove only when installing on 2-transformer system.
- Use either O or B terminals for changeover valve.
- A 24 VAC 500mA common connection is required with this thermostat.
Note: Devices such as a float switch that mechanically break circuits should be installed so that they break the control wire (Y) not the power (R). Interrupting the power circuit will shut off power to the thermostat completely and not allow it to operate.
Installation Tip
Max Torque = 6in-lbs.
Do not overtighten terminal block screws, as this can damage the terminal block. A damaged terminal block can keep the thermostat from fitting on the subbase correctly or cause system operation issues.
Replacement Thermostat Wiring
- If you are replacing a thermostat, make note of the terminal connections on the thermostat that is being replaced. In some cases the wiring connections will not be color coded. For example, the green wire may not be connected to the G terminal.
- Loosen the terminal block screws. Insert wires then retighten terminal block screws.
- Place nonflammable insulation into wall opening to prevent drafts.
- This thermostat requires a 24V common wire to the C terminal.
Caution: Electrical Hazard
Failure to disconnect the power before beginning to install this product can
cause electrical shock or equipment damage.
Warning:
All components of the control system and the thermostat installation must
conform to Class II circuits per the NEC Code.

Technician Setup Menu
This thermostat has a technician setup menu for easy installer configuration. To set up the thermostat for your particular application:
- Press and hold the + and – buttons for 3 seconds.
- Press and hold the TECH button for 3 seconds.
- Configure the installer options as desired using the table below. Use the + or – buttons to change settings and the lower left and right buttons to move from one step to another.
- To exit tech setup: press and hold the + and – buttons for 3 seconds, or wait 60 seconds.
Swing Setting Tip
Temperature swing, sometimes called differential or cycle rate, can be
customized for this individual application. For most applications choose a
swing setting that is as long as possible without making the occupants
uncomfortable.
Swing Setting Tip
The second stage will turn on at 2x the swing setting. The second stage will
turn off when 1x the swing is reached. For example, if the swing setting is .5
degrees for heating and the thermostat is set at 70˚F, the first stage will
turn on at approximately 69.5˚F. The second stage will turn on at 69˚F. The
second stage will turn off at 69.5˚F and the first will turn off at 70.5˚F. If
the third stage is used, it will turn on at 68.5˚F and turn off at
approximately 69˚F.
These tech settings will only appear once the thermostat has been connected to the App.
WIFI Setup
The following WIFI Technician steps are intended for viewing information and resetting your WIFI connection. They are not typically necessary for installation or initial setup.
- Press and hold the + and – buttons together for 3 seconds.
- Press and hold the WIFI Button on the lower left.
- Use the + or – buttons to change settings and the lower left and right buttons to move from one step to another. To exit tech setup: press and hold the + and – buttons for 3 seconds or wait 60 seconds.
WIFI Reset Process
This step resets the WIFI connection when needed for applications like replacing WIFI routers, changing networks, or any other time you might need to disconnect and reconnect your thermostat to a local WIFI network.
- Enter the WIFI Menu and cycle through the steps until you get to the RESET WIFI setting.
- Hold the + button for three seconds.
- You will now be automatically returned to the home screen and “WIFI RESET” network will be displayed indicating the thermostat is no longer connected to the local WIFI network. You will need to recommission the thermostat to control your system from the PRO1 Connect App.
